Arboricultural Method Statement – Land at Barrow Brook, Barrow, Clitheroe (15/05/2013) 1

SEQUENCE OF OPERATIONS

From commencement of the above development, the following methodology shall be implemented in the manner and sequence described:

1. Pre-contract site meeting 2. Tree Surgery Works 3. Erect temporary protective fencing 4. Excavation for trial trenches within the RPA of tree numbers 4 & 8 5. Ground protection within RPA of tree number 12 6. Main construction phase 7. Installation of ‘No-Dig’ access road with RPA of tree number 10 8. Removal of temporary fencing 9. Landscaping within RPA’s 10. Arboricultural Site Supervision

1. Pre-Contract Site Meeting

To outline working methods in relation to trees prior to any construction activity on site, a site meeting of the following shall take place:

1. Client Main 2. Contractor 3. Tree Solutions Ltd 4. LPA Tree Officer

2. Tree Surgery Works

1. Before the erection of the temporary protective fencing, all tree removal shall be implemented in accordance with the Tree Survey Schedule at Appendix 1

2. All possible efforts must be made to prevent damage to retained trees including potential root incursion or compaction caused by vehicle access.

3. All arboricultural works shall conform to the recommendations of BS 3998 (2010) ‘Recommendations for Tree Work’

4. All operatives shall be equipped with and use personal protective equipment (PPE) in accordance with current Health & Safety Executive current directives and industry codes of practice.

5. Performance of all arboricultural operations and use of equipment shall be in accordance with current Health & Safety Executive current directives and industry codes of practice.

3. Temporary Tree Protective Fencing Erection

1. Following completion of the tree felling and prior to commencement of any site demolition, construction, preparation, excavation or material deliveries the main contractor shall erect the temporary protective fencing as detailed in the ‘Tree Protection Specification’ and in the location indicated on the Tree Protection Plan.

4. Excavation of tree root inspection trench within RPA of tree numbers 4 & 8

The trial trench will be excavated in the location indicated on the Tree Protection Plan by hand digging or by use of an ‘Airspade’.

1. The exploration trench will be excavated to the full foundation depth of the proposed road in order to ascertain the presence of roots. If roots larger than 25mm are found to be present within the trench, the LPA tree officer will be notified prior to any further action taking place. If roots are found to be significant and therefore not appropriate to prune, the pedestrian footway specification will be amended to a ‘No-Dig’ design, details of which will be submitted for approval.

2. Should planning consent be granted for construction within the RPA of these trees, the required excavation should be carried out by a small tracked excavator and under the direct supervision of Tree Solutions Ltd. Any tree roots found during the excavation will be cleanly severed rather than ripped from the ground. Roots, whist exposed, shall be wrapped in dry (winter) or wet (summer), clean Hessian sacking to prevent desiccation

Arboricultural Method Statement – Land at Barrow Brook, Barrow, Clitheroe (15/05/2013) 2

and to protect from rapid temperature changes. Exposed roots shall be pruned back to a side branch, by use of a sharp saw or secateurs.

5. Ground protection within RPA of tree number 12

1 The ground protection will involve the use of a temporary plywood boards laid across the RPA that extends beyond the protective fencing location butted together to form a continuous line as indicated on the Tree Protection Plan. The boards will be fixed in place by construction tie-rods to avoid any displacement.

2 The ground beneath any protection boarding will be left undisturbed and will be

protected with a porous geotextile fabric and side butting scaffold boards on a 100mm compressible layer such of sharp sand.

6. Main Construction Phase

1. There shall be no storage of construction material, site parking, site accommodation or equipment in any area designated as the Root Protection Area (RPA) and Construction Exclusion Zone (CEZ) and enclosed by Temporary Protective Fencing

2. No materials that are likely to have an adverse effect on tree health such as oil, bitumen or cement will be stored or discharged within 10 metres of the trunk of a tree that is to be retained. No fires will be lit.

3. The site agent shall supervise deliveries by self-loading crane, with vehicles positioned in such a manner that retained trees are not at risk of damage. Avoiding Damage to Stems and Branches

4. Care shall be taken when planning site operations in proximity to trees to ensure that wide or tall loads or plant with booms, jibs and counterweights can operate without coming into contact with retained trees. Such contact can result in serious injury resulting in safe retention impossible

On Site Storage of Spoil and Building Materials 5. Prior to and during all site construction works no spoil will be stored within the crown

spread on any tree on or adjacent to the site even if proposed site work is to be within

Arboricultural Method Statement – Land at Barrow Brook, Barrow, Clitheroe (15/05/2013) 3

the crown spread. Any encroachment within this protected area will only be with the prior agreement of the LPA Arboricultural Officer.

7. Installation of ‘No-Dig’ Access Road Adjacent to Tree Number 10

1. Upon completion of all construction work and removal of all plant and material from site, the vehicular access shall be constructed using a no-dig three dimensional cellular confinement system in accordance with the engineers and manufacturers recommendations see example drawing below.

2. Construction shall ideally be undertaken in dry weather when ground is driest and least prone to compaction

3. Ground vegetation should be killed using a translocated herbicide such as glyphosate. To prevent severe oxygen depletion in the soil during the process of decomposition, all dead organic material shall be removed

4. All major protrusions such as rocks and demolition material shall be removed minimizing ground disturbance. All hollows will be filled with sharp sand

5. Permeable matting will then be laid and the cellular confinement system laid on top and pegged in place.

6. The cellular confinement system will then be installed in accordance with the manufacturer’s guidelines using no-fines aggregate. Fill the cells working from the

area furthest from the tree first. Further filling should be carried out using the filled Cellweb as a platform

7. Edging will be constructed with tantalised boards attached to pegs driven into the ground. Pegs should be long enough to give adequate support during construction

8. Install a permeable wearing course, e.g. block paviours or porous tarmac placed on the aggregate. Paving slabs or brick paviours should be dry-bedded on the sub-base and joints left unsealed

9. Tree Solutions will be responsible for monitoring all excavation works and issuing a certificate of practical completion

10. Under no circumstances is limestone aggregate to be used

8. Remove all Temporary Tree Protective Fencing

1. Tree Protective fencing will only be removed upon completion of all construction work and once all machinery associated with the works has left site.

9. Landscaping within the RPA of trees

1. Landscaping works will be implemented in accordance with a scheme approved by the LPA

2. There shall be no rotovation of ground within any area designated as a Root

Protection Area (RPA) and Construction Exclusion Zone (CEZ) and enclosed by Temporary Protective Fencing.

3. No hard landscaping works or excavation for cables or any other service should be installed within the Root Protection Area (RPA) and Construction Exclusion Zone (CEZ) without the written consent of Planning Service.

TREE PROTECTIVE FENCING

1 Before the commencement of any demolition and subsequent construction works on site (other than those set out in the schedule of tree works contained in this document), protective fencing will be erected as detailed on the Tree Protection Plan and as specified below. The LPA Tree Officer will be given 5 days notice upon completion of the fencing in order to inspect and approve prior to the commencement of any site works.

2 The fencing will consist of a scaffold framework in accordance with Figure 2 of BS 5837

– 2012 (illustration below) comprising a metal framework, both vertical and horizontal, well braced to resist impacts. Vertical tubes will be spaced at a maximum interval of 3m. Onto this, weldmesh panels shall be securely fixed with wire or scaffold clamps. Weldmesh panels on rubber or concrete feet are not considered resistant to impact and for this reason will not be used. The site manager or other suitably qualified appointed person will be responsible for inspecting the protective fencing on a daily basis; any

damage to the fencing or breaches of the fenced area will be rectified immediately. 3 Clearly legible weatherproof signage, stating “Protected Trees – Exclusion Zone” shall

be attached to the fencing 1.5m from the ground, facing out of the Tree Protection Zone located at regular intervals along the fence line.

4 The fencing will remain in place until completion of all site works and then only removed

when all site traffic is removed from site. 5 Other than works detailed within this method statement or approved in writing by the

Local Planning Authority (LPA), no works including storage or dumping of materials shall take place within the exclusion zones defined by the protective fencing.
